FILM-PACKAGE AND HOLDER.

Application filed September 30, 1912.

To all whom it may concern:

Be it known that I, WILLIAM T. PRICE, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented a new and useful Improvement in Film-Packagesand Holders, of which the following is a specification.

This invention relates to an exposure appliance for photographic filmsor plates and is adapted to provide efficient and effective means forloading a plate holder in day light. Devices of this character whichhave heretofore been used have either been too complicated orinefiective in use to be practical and it is the primary object of myinvention to provide simple, effective and inexpensive means forovercoming these ob-- jections.

A further object of my invention 1s to provide an improved appliance ofthe character specified which can be used with any ordinary plate holderwithout changes.

In the drawings forming part of this specification Figure 1 is aperspective of a plate holder showing my invention applied thereto, theenvelop which is employed being partially withdrawn; Fig. 2 is anotherperspective of the plate holder show.- ing the envelop inserted but inclosed position; Fig. 3 is an enlarged detail in section of the plateholder showing my invention applied to each side thereof, the fiap ofthe envelop in the upper side of the holder being clamped below thehinged end of the holder and the flap on the envelop in the lower sideof the holder is closed position;

the hinged end of the holder on the lower side of the holder being inpartly open position; Fig. 4 is a plan of the film and film mount; Fig.5 is a section taken on the line A-A, Fig. 4; Fig. 6 is a longitudinalsection of the envelop; Fig. 7 is a perspective of the envelop inclosinga film therein; Fig. 8 is a section of Fig. 7 taken on the line BB, andFig. 9 is a perspective of what I have chosen to term the adapter.

In the drawings A indicates a plate holder of usual construction havinga rectangular frame composed of two opposite parallel sides 2 and 3 andopposite end 4. Secured in the sides and ends of the plate holder andlying centrally disposed in a plane parallel with the front and backfaces thereof is a partition 5 of usual construction. On both sides ofthis partition Specification of Letters Patent.

longitudinal slots 6 and 7 are formed in the sides 2 and 3 0f the holderand spaces are left between the end pieces 8 and the partition whichcommunicate with the slots 6 and 7 whereby a film package composed of anenvelop 9 and film can be inserted and withdrawn from the holder oneither side of partition 5 in the usual manner. The end 1 of the plateholder is provided with hinged flaps 8 the method of hinging being bymeans of a strip of flexible material 10 glued or otherwise secured tothe end 4: and the edge portions of said flaps whereby said flaps arefree to swing out from a posi tion flush with the surface of said plateholder. The plate holder thus described is of ordinary construction andthe film package constructed in accordance with my invention is adaptedto be applied thereto.

The film mount 11 in the form of a sheet or plate made of any suitablematerial such as card board has secured in fiat condition upon itssurface by gluing or any other suitable means a photographic film 12.One end of the mount 11 is formed with a flap 18 and has secured to itsback a tongue 14 by gluing or any other suitable means. The projectingend of the tongue is perforated at 15. Vhen the film package is loadedprevious to its application to the plate holder the film mount isinclosed by the envelop with its flap 13 sealed over the surface of theenvelop as illustrated in Fig. 7. While in this position and with itssealed end first the film package may be slid in the slots in the sidesof the frame on either side of the partition 5, into the positionillustrated in Fig. 2.

Positioned on either side of the partition 5 and between said partitionand either of said film packages is what I have chosen to term anadapter 17 in the form of a plate made of card board or any othersuitable material. This adapter drops freely be tween the sides and endsof the plate holder before the film package is placed in said holder andis spaced with its surface out of contact with the film package. Eachadapter has upon its inner end which is adapted to adjoin one of theflaps 8, a guard in the form of a strip folded or pinched over the inneredge of the adapter, said strip being formed with upturned edge 19facing inwardly as illustrated and a spring catch 20 having a key 21which is adapted to enter the perforation 15 in the tongue 1a to edge 19of the guard is adapted to receive the fold crease of the fiap of thefilm mount and the flap of the film mount is adapted to be turned backover the guard 19 and clamped below one of the flaps 8 as illustrated inFig. 1. In this position the guard 19 serves to hold the flap out of theway during an exposure in the camera and prevents light leaking into theenvelop before the envelop is withdrawn and before the plate holder isplaced in the back of the camera. The guard strip has its body andupturned edge 19 notched at 25 said notch extending through the adapterplate to admit the key 21 freely through the tongue 14:. The springcatch 20 is secured to the upper edge of the guard and its tendency isto press and hold its key 21 engaged through the tongue 1 1. The catch20 may be lifted against its tension until its key is lifted out ofengagement with the tongue so that after the flap 13 has been resealedover the face of the envelop both the envelop and the film with itsmount can be withdrawn simultaneously by pulling upon the extension16-of the envelop.

In order to assist in making the joint between the film mount andenvelop light.

proof and to prevent the film mount from tearing the end edges of theenvelop, clips 22 made of cloth or any other suitable ma terial may besecured over the end corners of the envelop by gluing or other suitablemeans, leaving the envelop free to slide upon the film mount. The guardelement may be secured by pinching its folded portion tight upon theadapter plate 17 or said strip can be glued or otherwise fastened uponthe otherwise fastened to the partition when de- 1 sired. It is howeveradvantageous to leave the adapters free to be inserted or removed fromthe plate holder without fastening 3 them to the partition thusproviding a plate holder free to be used either with plates in theordinary manner or with my improved film package when desired.

In use the fihn package is first inserted in the plate holder asillustrated in Fig. 2 and the key 21 lifted into engagement with thetongue 1-1- by releasing the catch 20 with its key into the slot 15. Theseal 23 over the flap 13 is then bro-ken and said flap turned back overthe guard 19 and catch 20 and the hinged end 8 turned down over the endof the flap 13 thus holding said flap in the position illustrated inFig. 1 while the envelop 9 remains i the position illustrated in theupper half of Fig. 3 and thus preventing light from leaking into theenvelop and spoiling the film. The plate holder may then be filled onits other side and placed in the back of the camera with an unexposedfilm side facing the lens in readiness for an exposure. The envelop 9 isthen withdrawn from over the unexposed film. After the exposure has beenmade the envelop is closed over the film in the holder and removed fromthe camera. The hinged end 8 is then lifted into superior position andthe flap turned down and sealed over the envelop. The catch can then beraised and the envelop with the film sealed therein withdrawn from theholder. It should be understood that the slots 6 and 7 in said holderare the same as the usual slots employed in the ordinary holder frame inwhich the usual light excluding slides are adjusted over sensitizedplates.

The terms film and plate as employed in the above description andfollowing claims should be considered synonymous as the use of eitherterm is intended to include the other and should be construedaccordingly.

In accordance with the patent statutes I have described the principlesof operation of inv invention together with the apparatus which I nowconsider to represent the best embodiment. thereof but I desire to haveit understood that the construction shown is only illustrative and thatthe invention can be carried out by other means and applied to usesother than those above set forth within the scope of the followingclaims.
